Let the previous price of apple be Rs. '10x' per piece So, new price of the apple = '10x' X 0.7 = Rs. '7x' ATQ: (140/7x) - (140/10x) = 5 or, (20/x) - (14/x) = 5 or, 6/x = 5 or, 5x = 6 x = 1.2 So, previous price of apples = 10 X 1.2 = Rs. 12 per piece
(3500 ÷ √1225) × √(20.25) = ? ÷ 4
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
136% of 560 - 2/7 of 630 + 45% of 420 =?
Determine the simplified value of the given mathematical expression.
1500 × 60% of 25% = ? 2
53 – 8 = ? + 126
Find the Value of
? = 6.25% of 240 + 25 2 + 17 2 – 16 × 17
